If you want an idea of what types of innovative products are going to burst into the mainstream - and want to give some financial support to make them a reality - Kickstarter's tech section is a great place to look. When it comes to tech, backers especially gravitate toward smartwatches, smart home and kitchen devices, and headphones.

While backing a Kickstarter project has potentially large payoffs, it's not without risk. Some projects are never fully produced or released, and others shut down after a few years, leaving backers with unexplained holes in their wallets or products with useless, outdated software.

Pono Music, Neil Young's studio quality MP3 player, is one of the top-funded projects in Kickstarter history, with more than $6 million pledged by 18,220 backers, but it was discontinued in 2017. Meanwhile, smartwatch startup Pebble racked up more than $43 million in funding for three of its projects before it filed for insolvency at the end of 2016. Its assets were ultimately acquired by Fitbit.

We've left such products out in this round-up to spare you that frustration. Each of these 25 tech projects will go down in Kickstarter history for raising more than $1 million, and they're actually worth your money.
